You have a car with seperate turn and brake lights. How will you blend those to a trailer with a shared brake turn signal filament bulb?
You can get an adapter at a UHaul store or car parts counter. My history with that danged thing was it had a tendency to fry. Made my own: no elecronics except the isolating diodes for brake and turn inputs to the relay which did the trailer shared lamp. Also a relay for taillights. A fused power wire ran from battery to one side of the power switching blades of the relays and frame ground to one side of the coils of each relay. Connect tail lamp wire to one coil and that relay powers trailer tails. Brake circuit on one diode and turn wire on other diode on other relay to isolate both but operate the trailer's brake and turn lamp. This will not have priority of turn over brake as on American car. Brake will have priority over turn with this setup.
You can add another tail lamp assemble on the trailer, run wire for it and you can have sep. turns on that. You won't need any adapter.
